Yes, the physical dimensions of the GH3 take it into dSLR territory, but they are not the only criteria that matter. The weight of the GH3 body only with battery is 550g, while the Canon EOS 6D tips the scales at 770g (again for body only with battery). That is a 40% increase in weight compared to the GH3 before you even start to consider the size and weight of the lenses and the cameras' relative suitability for those of us with large hands or a taste for quality video recording.

If small size is what really matters for you then the GH3 is not the camera for you. Take a look at a Pen mini or a GF5.

I have 3 pens, and a GF1, and few lenses including the pany 20mm and the 7-14mm.

For ultralight, the OMD looks to be the best choice. For hybrid still/video use, the GH3 looks much better, albeit with a modest weight penalty. But the Canon...

Wow, that thing looks like a monster! Huge and heavy. Lacks necessary features for video (GH3 wins for that) and has a massive weight penalty for stills (GH3 is good and OMD is great for that). The 6D is a nice camera, but I'd hate to lug that thing around all day.

Dan.

p.s. Be careful when using specs and tools like camerasize.com to support your point. Other people have access to the same specs to make the exact opposite argument. And for folks like me who HAVE lugged around large cameras like that, size and weight are a major turnoff.

The GH3 is sitll substantially smaller, especially with a lens. I mean, a Chevy Tahoe is "only" 10 inches longer than a Honda Accord. But go drive them both and the Tahoe will feel huge in comparison. I see this kind of the same way. Sure, the GH3 isn't a Fiat 500, but it's hardly a Tahoe or Suburban, either.

Actually, larger cameras are a non-issue for video work. Something like the GH3 or 6D will be put in a rig for better ergonomics and so that other components can be used like follow focus, or lighting. Shooting a DSLR in video work, handheld is somewhat noobish... its not the ideal form factor at all.

Yes, GH3 is way too large! Unfortunately while designing the GH3 Panasonic didn't consider the army of enthusiasts shooting with body only. For the rest though there is some evidence of size difference between GH3+12-35mm and 600D+24-70mm/24-105mm:

The Nikon Z6 may not offer the incredible resolution of its sibling, the Z7, but its 24MP resolution is more than enough for most people, and the money saved can buy a lot of glass. Find out what's new and notable about the Z6 in our First Impressions Review.

Many cameras today include built-in image stabilization systems, but when it comes to video that's still no substitute for a proper camera stabilization rig. The Ronin-S aims to solve that problem for DSLR and mirrorless camera users, and we think DJI has delivered on that promise.

The SiOnyx Aurora is a compact camera designed to shoot stills and video in color under low light conditions, so we put it to the test under the northern lights and against a Nikon D5. It may not be a replacement for a DSLR, but it can complement one well for some uses.

At its core, the Scanza is an easy-to-use multi-format film scanner. It offers a quick and easy way to scan your film negatives and slides into JPEGs, but costs a lot more than similar products without a Kodak label.
